EPSS Score:
1%
Comprehensive Technical Analysis of EUVD-2024-41390
1. Vulnerability Assessment and Severity Evaluation
Vulnerability Description: The vulnerability identified as EUVD-2024-41390 pertains to Elsight's Halo version 11.7.1.5, which is susceptible to OS Command Injection (CWE-78). This type of vulnerability occurs when an application improperly neutralizes special elements used in OS commands, allowing an attacker to execute arbitrary commands on the host operating system.
Severity Evaluation:
The CVSS (Common Vulnerability Scoring System) base score of 9.8 indicates a critical severity level. The vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H breaks down as follows:
- Attack Vector (AV): Network (N) - The vulnerability can be exploited remotely over the network.
- Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources to exploit.
- Privileges Required (PR): None (N) - No special privileges are needed to exploit the vulnerability.
- User Interaction (UI): None (N) - No user interaction is required for the attack to succeed.
- Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
- Confidentiality (C): High (H) - The vulnerability can lead to a significant breach of confidentiality.
- Integrity (I): High (H) - The vulnerability can lead to a significant breach of integrity.
- Availability (A): High (H) - The vulnerability can lead to a significant breach of availability.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Remote Command Execution: An attacker can send crafted input to the vulnerable application, which is then executed as an OS command.
- Phishing and Social Engineering: Attackers may use social engineering techniques to trick users into interacting with malicious links or files that exploit the vulnerability.
Exploitation Methods:
- Injection of Malicious Commands: Attackers can inject malicious commands into input fields that are not properly sanitized, leading to arbitrary command execution.
- Chaining with Other Vulnerabilities: This vulnerability can be chained with other vulnerabilities to escalate privileges or gain deeper access into the system.
3. Affected Systems and Software Versions
Affected Systems:
- Elsight Halo version 11.7.1.5
Software Versions:
- The vulnerability affects Elsight Halo version 11.7.1.5. Users are advised to upgrade to version 11.9.4.0 to mitigate the risk.
4. Recommended Mitigation Strategies
Immediate Actions:
- Upgrade Software: Upgrade to Elsight Halo version 11.9.4.0 or later.
- Input Validation: Implement robust input validation and sanitization mechanisms to prevent the injection of malicious commands.
- Least Privilege Principle: Ensure that the application runs with the least privileges necessary to minimize the impact of a successful exploit.
Long-Term Strategies:
- Regular Patching: Establish a regular patching and update schedule to ensure that all software is up-to-date.
- Security Training: Conduct regular security training for developers and users to recognize and mitigate potential vulnerabilities.
- Monitoring and Logging: Implement comprehensive monitoring and logging to detect and respond to suspicious activities promptly.
5. Impact on European Cybersecurity Landscape
Regional Impact:
- Critical Infrastructure: The vulnerability poses a significant risk to critical infrastructure, especially in sectors relying on Elsight's Halo software.

- Economic Impact: Successful exploitation can result in financial losses due to data breaches, system downtime, and recovery costs.
Regulatory Compliance:
- Organizations must ensure compliance with EU regulations such as GDPR and NIS Directive, which mandate robust cybersecurity measures and incident reporting.
6. Technical Details for Security Professionals
Detection and Response:
- Intrusion Detection Systems (IDS): Deploy IDS to detect unusual command execution patterns that may indicate an exploit attempt.
- Endpoint Detection and Response (EDR): Use EDR solutions to monitor and respond to suspicious activities on endpoints.
- Security Information and Event Management (SIEM): Integrate SIEM systems to correlate and analyze security events for early detection of threats.
Incident Response Plan:
- Preparation: Develop and regularly update an incident response plan tailored to OS Command Injection vulnerabilities.
- Detection and Analysis: Implement tools and processes to detect and analyze potential incidents quickly.
- Containment, Eradication, and Recovery: Establish procedures for containing the incident, eradicating the threat, and recovering affected systems.
- Post-Incident Activity: Conduct a thorough post-incident analysis to understand the root cause and improve defenses.
Conclusion: The EUVD-2024-41390 vulnerability in Elsight's Halo version 11.7.1.5 is a critical threat that requires immediate attention. Organizations must prioritize upgrading to the latest software version, implementing robust security measures, and ensuring compliance with relevant regulations to mitigate the risk effectively.
